My garden always fills up fast when I'm working on something new - you know gotta work out all the bugs of how to attach things. Can't weld glass, but need to attach to steel.... what hardware holds this or that...it's all a process. I consider all these prototypes of sort, but in the end my garden is all the better for it.
Maybe someday I can stop creating art that is a real pain to ship/move and load!....but
if truth be told I can't wait to get back to the thrift store and buy some more junk.
